Your answer is D (19). You can get this answer by plugging it into the equation (n - 2)x180 = total degrees. Once you substitute 19 in for n (number of sides) and 3060 in for the degree amount, your equation will look like this: 

(19 - 2)x180 = 3060
The answer is 19. You would solve it like this 19 - 2 x 180 and that equals 3060. So your answer is 19 D
